// Extended Element: XRingGauge
// - Creates display element similar to a donut-chart.
// - The element has an outer and inner radius to create a ring appearance.
// - The ring has an angular range defined by SetAngleRange, which means that
// the ring can be configured to cover a full circle or just a portion of
// a circle.
// - SetAngleRange defines the starting angle and direction of fill.
// - When drawing the ring within the angular range, it is composed of
// an active region (the angular region from the start to the current
// position value) and an inactive region (from the current value to the
// end of the angular range). The inactive region can be hidden (by
// setting it to the background color).
// - A text value can be drawn in the center of the ring, typically to
// show the current value. The color defined by SetColorBackground() is
// used when redrawing the text.
